Web19 dec. 2024 · This paper explores how we can leverage recent advances in 5G millimeter wave (mmWave) technology for imaging in self-driving cars. Specifically, the use of mmWave in 5G has led to the creation of compact phased arrays with hundreds of antenna elements that can be electronically steered. Such phased arrays can expand the use of …
WebActive millimeter-wave (MMW) imaging technology operates as short-range radar (radio detection and ranging) systems with a wavelength from 10mm to 1mm (i.e. 30 to 300GHz). MMW technology has been shown that it can penetrate though dielectric materials, such as plastic or cloth, and are strongly reflected by metallic materials.
